The relationships that students establish with pairs are important to their learning and to their psychosocial and cognitive development. In view of this, this study presents the construction and evidence of the validity of the Pair Interaction Scale for higher education students. 1070 university students with an average of 23 years of age (SD=6.5) participated in the research. The exploratory factor analysis indicated a multidimensional structure, composed of the factors: social interactions, intimate interactions, academic interactions related to offering help and academic interactions with emphasis on receiving help. The confirmatory factor analysis highlighted the suitability of the data to the factor structure (CFI=0.978; GFI=0.980; RMSEA=0.06). The regression coefficients of the items in relation to the factors were satisfactory (0.55<ß<0.86) and the indicators of internal consistency of each factor are suitable (0.72<α<0.85). Such results signal the existence of acceptable psychometric parameters and efficiency in the utilization of the instrument is suggested.
